Hmmm... Could anyone clarify if there is hurricanes during Fall? >_>
So far as HM goes, I know only two natural calamities that Marvelous incorporate in their HM games, which is Summer=Typhoon and Winter=Blizzard.
While playing IoH, I wasn't able to experience Hurricanes during Fall. Is this a new add-on in SI?
SI still follows the classic hm ways and the logical times for things to occur. Theres only two types of storms in only 2 seasons. Hurricanes/typhoons in summer and blizzards in winter. So to answer your question, no there is no hurricanes in fall.
EDIT: oh sorry I didn't see your question was answered. I failed to check if it was-brain fart. I'm having quite a few of those today.
